A study published at the American Society for Experimental Biology showed that drinking coffee can increase the muscle strength of the elderly and reduce their chances of falling.
In order to explore whether caffeine can enhance the muscle strength of the elderly, the sports scientists at Coventry University in the United Kingdom chose mice for experiments. To investigate the effects of caffeine on muscle strength, the researchers classified the muscle types of mice according to their age.
The study found that caffeine can enhance the muscle strength of two different skeletal muscles in mice, but this effect is not apparent in young mice, but it is more obvious in older mice. Jensen Tarris, the author of the study, believes that caffeine has a beneficial effect on the muscle strength of the elderly, so it can be consumed in moderation. The total amount of caffeine intake per day is preferably no more than 250 mg, which is equivalent to 2 cups of coffee.
